Best Mode for Carrying Out the Invention

The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

Example

As shown in Figures 1 to 5:

The present invention provides a multi-screen switchable monocular telescope rangefinder, comprising a rangefinder body 11 and a mounting cylinder 12 mounted at the bottom of the rangefinder body 11. A laser emitting assembly is mounted in the mounting cylinder 12 for emitting a ranging laser at a target. A laser receiving assembly is correspondingly disposed in the rangefinder body 11 for receiving a reflected laser signal. The laser receiving assembly includes a prism assembly 31. The prism assembly 31 is mounted in the rangefinder body 11 and can reflect the received laser signal. To achieve multi-screen display, a mounting cavity 13 is disposed at the bottom of the rangefinder body 11. The mounting cavity 13 is aligned with the built-in prism assembly 31, and a screen display assembly is correspondingly disposed in the mounting cavity 13.

As shown in Figures 1 and 2, a battery 14 is provided at the bottom of the rangefinder body 11, a key circuit board 47 is provided at the top, and a circuit board 48 is provided on one side of the rangefinder body 11. The battery 14, laser receiving component, laser emitting component and key circuit board 47 are all electrically connected to the circuit board 48; thereby, the circuit board 48 provides continuous and stable power support for the built-in laser receiving component and laser emitting component. Since laser emission and reception require a large amount of electric energy to drive, using the battery 14 as a power source can effectively avoid the problem of decreased ranging accuracy due to unstable power supply. Moreover, compared with an external power supply, the built-in battery 14 can make the entire rangefinder smaller and more convenient to hold.

Please refer to Figures 2, 4 and 5. The laser emitting assembly includes a laser emitting module 21. The laser emitting module 21 is arranged in the mounting cylinder 12. The laser emitting module 21 is electrically connected to the circuit board 48 to obtain power from the battery 14, which can ensure the stability of the laser emission. In addition, an emitting lens fixture 22 is fixed to one end of the mounting cylinder 12 by a thread, and a laser emitting optical module 23 is correspondingly installed in the emitting lens fixture 22. In order to achieve laser emission, the laser emitting module 21 is facing the built-in laser emitting optical module 23, and the laser is emitted toward the target through the laser emitting optical module 23.

As shown in FIG2 , the laser receiving assembly further includes an objective lens assembly 32. An objective lens fixture 33 is threadedly fixed to one end of the rangefinder body 11. The objective lens assembly 32 is mounted within the objective lens fixture 33 and serves to collect light. Simultaneously, a prism assembly 31 is secured within the rangefinder body 11 via a prism fixture 34. The prism assembly 31 primarily refracts the collected light. The objective lens assembly 32 collects the returning laser light inward, while the prism assembly 31 refracts the light.

As shown in Figures 2 and 5 , to achieve accurate distance measurement, a laser receiver module 35 is disposed at the bottom of the rangefinder body 11. The receiving surface of the laser receiver module 35 faces the bottom of the prism assembly 31 located within the body. This allows light refracted by the prism assembly 31 to directly enter the laser receiver module 35. Furthermore, the laser receiver module 35 also obtains output power from the battery 14 through an electrical connection to the circuit board 48. This stable power supply ensures efficient operation of the receiver.

As shown in Figures 2 and 4, the display assembly includes a reflective OLED liquid crystal 41, which is installed in the installation cavity 13 and can clearly display the distance measurement results. At the same time, a reflector 42 is provided at the bottom of the installation cavity 13, and a reflector adjustment module 43 is further installed below the reflector 42. In order to transmit light, a lens group 44 is also provided in the installation cavity 13. One end of the lens group 44 faces the reflector 42, and the other end is connected to the prism group 31. This ensures that the distance measurement results displayed on the reflective OLED liquid crystal 41 can be smoothly transmitted from the prism group 31 to the image surface of the objective lens group 32.

As shown in Figures 2 and 3, an eyepiece assembly 15 is provided at one end of the rangefinder body 11. A transmissive LCD 46 is provided between the eyepiece assembly 15 and the rangefinder body 11 to display the distance measurement results. The transmissive LCD 46 and the reflective OLED 41 are both electrically connected to a circuit board 48. A key circuit board 47 allows the user to switch between the reflective OLED 41 and the transmissive LCD 46. This allows the rangefinder to select the optimal display mode in various indoor and outdoor environments. Furthermore, the key circuit board 47 can also adjust the font color and brightness to suit viewing conditions under varying lighting conditions.

The eyepiece assembly 15 is also provided with an eyepiece focusing wheel 16. By rotating the eyepiece focusing wheel 16, the user can quickly and easily focus on the target and clearly define the observation range. The rangefinder uses a screen display component that simultaneously uses a reflective OLED liquid crystal 41 and a transmissive LCD liquid crystal 46 for multi-screen display, solving the problem that traditional monocular telescope-type rangefinders can only display a single display.

Modes for Carrying Out the Invention

The specific usage and function of this embodiment are as follows: During use, laser light is emitted by the laser emitting module 21. After passing through the laser emitting optical module 23, the laser light hits the target surface and is reflected back. After passing through the objective lens group 32 and the prism group 31, the laser light reaches the laser receiver module 35, and the distance measurement result can be obtained. The transmissive LCD liquid crystal 46 is installed between the eyepiece group 15 and the prism group 31, and the measurement result is displayed on the imaging focal plane of the eyepiece group 15. The measurement result display at the installation position of the reflective OLED liquid crystal 41 is displayed by refraction and reflection by the reflector 42, optical path adjustment by the lens group 44, and refraction and reflection by the prism group 31. The measurement result displayed by the reflective OLED liquid crystal 41 can be observed in the eyepiece group 15. The installation position of the reflective OLED liquid crystal 41 is the position of another focal plane formed by the above lens group 44, the prism group 31, and the reflector 42. The measurement result display of the transmissive LCD liquid crystal 46 and the reflective OLED liquid crystal 41 can be switched by the control of the key circuit board 47.

During production and installation, the objective lens group 32 and the prism group 31 are adjusted and fixed through the objective lens fixing member 33 and the prism fixing member 34 respectively; the laser emission optical module 23 is adjusted and fixed through the emission lens fixing member 22, so that the laser emission and return reception can achieve the best optical signal effect.

During production and installation, the reflector adjustment module 43 is adjusted to adjust the reflector 42 and the lens group 44 is adjusted through the lens fixing member 45 and then fixed, so that the display of the reflective OLED liquid crystal 41 can achieve the best display effect when observed through the eyepiece group 15; when in use, the observation target and display clarity can be adjusted through the eyepiece focusing wheel 16.
